High-precision turning

We create complex turned parts that meet your precision requirements for your most ambitious industrial projects.

Our expertise and precision at the service of your industry

High-precision turning requires technical expertise and rigorous execution. This involves removing chips by rotating the future part around its axis while moving the cutting tool. This method produces cylindrical, conical or spherical surfaces with excellent geometric quality and controlled surface finishes.

At Clément SA, we combine conventional lathes and specialised machines to produce your turned parts with strict dimensional tolerances. From prototypes to large production runs, we guarantee the conformity of every dimension.

Our turning capabilities

  • Maximum diameter: Ø660 mm
  • Maximum length: 3000 mm
  • Guaranteed precision: 7 to 8 microns
  • Production: single parts, medium and large series
  • Quality control: all our parts are checked on our ZEISS 3D measuring machine.

Our ZEISS three-dimensional quality control centre (OMC850)

  • ZEISS three-dimensional (OMC850) 850 x 1200 x 800 mm
  • ZEISS three-dimensional (MS850) 850 x 1200 x 800 mm
